Official TypeScript Recipes for Coding Assistant

Codiga's TypeScript Recipes

Converts a color code to an rgb() or rgba() string if alpha value is provided.

Hex to RGB

Converts a number to an array of digits, removing its sign if necessary.

Number to digits

Creates an array of numbers in the arithmetic progression, starting with the given positive integer and up to the specified limit.

Arithmetic Progression

Calculates the sum of the powers of all the numbers from start to end (both inclusive).

Sum of powers

Calculates the distance between two points in any number of dimensions.

Euclidean Distance

Generates primes up to a given number, using the Sieve of Eratosthenes.

Primes

Returns the ISO format of the given number of seconds.

Format seconds

Max value in array

Min value in array

Returns the human-readable format of the given number of milliseconds.

Format duration

Sorts an array of numbers, using the selection sort algorithm.

Selection sort

Construct a type that excludes properties from the given interface.

Omit type interface

Construct a new type based on some properties of an interface with the Pick utility type

Pick type interface

return a state array with two values using useState hook

React useState

Create input and use React.createRef API to set up a reference by initializing it as null and declaring the HTML type

React input with reference

Define a button with ReactNode type for children

React children

Pass down reference and apply the prop type to a Button

React button element

Pass down reference and apply the prop type to a SVG

React svg element

Create an object without exposing the creation logic to the client and refer to newly created objects using a common interface.

Factory class

Prototype is a creational design pattern that lets you copy existing objects without making your code dependent on their classes.

Prototype Class

Singleton is a creational design pattern that lets you ensure that a class has only one instance, while providing a global access point to this instance.

Singleton class

The never type represents the type of values that never occur. For instance, never is the return type for a function expression or an arrow function expression that always throws an exception or one that never returns; Variables also acquire the type never when narrowed by any type guards that can never be true.

Never function

The type void is a little like the opposite of any: the absence of having any type at all.

Void function

Count the frequency of character in the string

Count char frequency
